I need to restore the power to the lift, but cannot figure out how to do it - am I missing something obvious?

Also, I have a question about the egg

Spoiler:

When I got it to lvl 30 it evolved and went down to level 25. Also, is the Hyperegg meant to have only 1hp and the Shell Armor ability (I can understand it working with Wonder Guard, but in this way...) and does it have a further evolution?
